Kids can collect a virtual “patch” with each episode they watch on certain Netflix shows.

Has Netflix found a way to encourage binge watching among children?

A new test feature from the streaming service is trying to turn TV watching into a trophy collecting game. Since early January, select Netflix users have been noticing the mysterious “patch collecting” feature.

On Friday, Netflix told PCMag that the feature was simply designed to make the viewing experience more fun. “We are testing a new feature on select kids titles that introduces collectible items for a more interactive experience, adding an element of fun and providing kids something to talk about and share around the titles they love,” the company said in an email.

The feature is available for shows including Fuller House, A Series of Unfortunate Events and Trollhunters, among others. Programs that offer patches feature a red unlock icon in the corner. However, collecting all the patches for a show doesn’t appear to unlock anything.

Children may like the feature, but at least a few parents have been less receptive.

.@netflix has patches /badges now? What’s the deal with this?? As if getting my son to stop watching Netflix wasn’t hard enough. Now I have to deal with him wanting to binge endless hours of shows just to earn a silly patch? Not good. My opinion I know, but still I don’t like it!

Some have been wondering if patch collecting will arrive for more adult Netflix programs like Stranger Things. Others have tweeted that the feature is better suited for TV shows that are actually educational for kids and warrant an achievement.

@netflix is now offering “patches” to children who watch their shows. Not a fan, but they understand the value of micro-credentials. What if this $2+ Billion company created QUALITY edu content (they created Stranger Things!), and offered badges to students. pic.twitter.com/thUA5QDns7
